then what do you do??? blow your money on the current dynasty 200 dx and hope nothing comes out anytime soon or wait???

There is "NOTHING" wrong with the dyn200. If a new unit comes out, i would bet it would be a bigger machine, and a more expensive one. The deal is, Miller or any other is not in any way obligated to tell you that a new product is coming out. Think about it, they would lose a lot of money! Besides if the dyn200 is worth it at its price today, it will be worth it tomorrow.

Ultimately how bad do you need the machine?!!!
New machines come out all the time, if you don't need it RIGHT now then wait to see what they come out with. If you need it before they come out with a new model then buy what fits your needs at the time. If you are able to wait but then don't like the machine they come out with anyway maybe you'll be lucky enough to get a deal on the previous version.
If you can afford to wait 2, 4, 6 , 8 months for the new model then you should probably ask yourself why your buying it in the first place.

Remember guys, these are welding machines, not high heels and handbags!!! You don't have to buy the new one to be in style for the fall fashion trend!

Only problem I have had with my Dyn200DX is the momentary HiFreq, and the erratic way it works, I just use LiftArc instead, but would like to know if something is wrong with my machine, my Syncrowave 250 does not react this way, any opinions....Paul

I could probably help if you would give a little better explanation of your HF problem. The Dynasty's are sensitive in respect to the tig start parameters so it may be as simple as changing a couple of the settings via hidden menu.

The HF starting appears to be one of the areas which the new version will address. Previously there was a single default start setting used erroneously by many for all different kinds of tungsten type and size, but which was intended for 3/32" diameter ceriated. I wouldn't say that the previous versions had problems as much as I would say the user didn't take the time to understand how to setup the machine properly--by reading the owner's manual. Sure you can just crank up the starting amperage and start duration, and it will light off just fine. The problem becomes undue wear on the tungsten. So the best compromise between consistent starts and long tungsten life becomes adjusting the parameters to only as much starting amperage and time as is necessary. For the comment about the syncro250...remember that HF is applied for both starting and continuous operation in AC mode, whereas it is only used for starting on the Dynasty model.

The new model appears to still have the generic starting mode for 3/32 dia. tungsten, but goes further by providing pre-set start parameters based upon the user's selection of tungsten diameter: 0.020, 0.040, 1/16, 3/32, and 1/8.

In addition, the range of starting adjustment has grown from being start amp, start time to start amp, start time, slope time, and min. amperage. So for those who hate to make adjustments other than the big dial for amperage, your best bet will be just to select the correct diameter of tungsten and that should give you good starts.

On another note, there also appears to be the ability to select different AC waveforms. Previously, AC was defined as 'Advanced Squarewave'. This offered a lot of puddle agitation due to its nearly vertical transition between DCEP and DCEN. Some in the past complained about silicon freezing in the puddle and giving a less than shiny final bead. Now you'll be able to choose the 'Soft Squarewave' which slows down the transition rate between DCEP and DCEN and provides less silicon freezing and better wetting at the toes of the bead. For the old-school users, a true sinusoidal waveform can be selected, as well as a triangle waveform.
